Several antipsychotics, but not mood stabilizers, were associated with the risk of pneumonia, which deserves our concern regarding patient safety. Some of the combinations of therapy resulted in synergy of risk.

A user-friendly instrument was developed to detect PIMs for Taiwanese older adults. Further prospective studies are needed to validate its use in clinical and research settings.

ObjectivesTaiwanese National Health Insurance (TNHI) provides home healthcare services to patients with skilled nursing needs who were homebound or lived in nursing homes. Studies on potentially inappropriate medications (PIMs) for older home healthcare service recipients (HHSRs) are growing, but comparisons among newer criteria of PIMs have not been applied. The aim of this study was to explore the prevalence and correlates of PIMs based on three different instruments published after 2010 among older HHSRs.Materials and MethodsWe performed cross-sectional analysis of the TNHI Research Database. A total of 25,187 HHSRs aged more than 65 years in 2009 were included. Medication lists independent of chronic conditions from the 2012 Beers criteria, PIM-Taiwan criteria, and the PRISCUS (Latin for “old and venerable”) criteria were used. Analysis was performed separately at patient and clinic-visit level. T-tests, chi-square analysis, and multivariate logistic regressions were used where appropriate.ResultsThe prevalence of having at least one PIM at patient and clinic-visit level was highest with the Beers (82.67%, 36.14% respectively), followed by the PRISCUS (68.49%, 25.13%) and PIM-Taiwan (63.04%, 19.21%) criteria. At patient level, polypharmacy (odds ratio (OR) 2.53 to 4.90), higher number of clinic (OR 1.15 to 1.41), hospital (OR 1.24 to 1.64), and physician (OR 1.15 to 1.41) visits were associated with PIM use for all 3 sets of criteria. At clinic-visit level, internist/family physicians (OR 1.26 to 1.72) and neurologists/psychiatrists (OR 1.73 to 5.87) were more likely to prescribe PIMs than others. Psychotropic drugs and first generation antihistamines accounted for most of the top ten PIMs.ConclusionThe prevalence of PIMs was high among older Taiwanese HHSRs. Polypharmacy and certain medical specialties were associated with a higher likelihood of PIM prescriptions. Provider education and medication review and reconciliation should be considered.

C ognitive impairment is a major contributor to disability and dependence worldwide. Globally, stroke is the leading cause of long-term disability among adults and the second leading cause of death.1 The high cumulative risk of dementia or stroke or both conditions has been shown by the Framingham study, 2 and the urgent need to improve knowledge regarding cognition and vascular conditions has been emphasized in a specific meeting providing harmonized standards. 3Beyond their personal tolls, both of these conditions carry substantial social and economic burdens. These conditions also correlate strongly with increasing age. Given the projected substantial rise in the number of older people around the world, prevalence rates of cognitive impairment and stroke are expected to soar over the next several decades, especially in high-income countries. 4,5 Shared pathophysiologic mechanisms seem to exist between cognitive impairment and cerebrovascular disease.6 Indeed, risk factors for stroke (hypertension, hyperlipidemia, diabetes, obesity and physical inactivity) have been shown to play a role in the onset and progression of cognitive impairment, 7 and it is well established that stroke itself increases the risk of future cognitive impairment. 8 However, whether cognitive impairment increases the risk of future stroke remains unclear. Early identification and regular surveillance for cognitive impairment could potentially enable prompt initiation of treatment aimed at not only potentially limiting further deterioration of cognitive function (if mild), but also possibly reducing the risk of future stroke through timely and optimal control of risk factors.Several published studies have assessed the association between cognitive impairment and subsequent risk of stroke, but the results have not been consistent. We performed a systematic review and meta-analysis to determine the qualitative and quantitative association between baseline cognitive impairment and risk of future stroke. Methods Search strategyOur search strategy was based on the recommendations of the Meta-analysis of Observational Studies in Epidemiology group. 9 We searched MEDLINE via PubMed (1966 to November Background: Several studies have assessed the link between cognitive impairment and risk of future stroke, but results have been inconsistent. We conducted a systematic review and meta-analysis of cohort studies to determine the association between cognitive impairment and risk of future stroke.

Background: Explicit criteria for potentially inappropriate medications (PIMs) developed for other countries are difficult to apply to a specific territory. This study aimed to update the PIM-Taiwan criteria from a qualitative review of several published PIM criteria, followed by consensus among regional experts in Taiwan. Methods: After a review of the literature, we selected four sets of published PIM criteria to construct preliminary core PIMs. The Beers criteria, Fit fOR The Aged (FORTA), and Japan criteria were used for PIMs, without consideration of chronic diseases. The Beers criteria, Screening Tool of Older Persons’ Prescriptions (STOPP) criteria, and Japan criteria were used for PIMs with respect to chronic diseases. We asked experts ( n = 24) to rate their agreement with each statement, including in the final PIM criteria, after two rounds of modified Delphi methods. The intraclass coefficient (ICC) was used to examine the reliability of the modified Delphi method. Results: Overall, two categories of PIMs were established: 131 individual drugs and 9 drugs with combinations that should generally be avoided; and 9 chronic diseases with their corresponding PIMs that have drug–disease interactions. The ICC estimates for PIMs to be avoided generally were 0.634 and 0.557 (round 1 and 2) and those for PIMs with respect to chronic diseases were 0.866 and 0.775 (round 1 and 2) of the Delphi method, respectively. Conclusions: The 2018 version of PIM-Taiwan criteria was established and several modifications were made to keep the criteria updated and relevant. Clinicians can use them to reduce polypharmacy and PIMs among older patients.

In patients experiencing pneumonia while undergoing clozapine treatment, physicians should carefully consider the increased risk of pneumonia recurrence when clozapine is reintroduced. Future studies should try to quantify the risk of other medical conditions associated with clozapine reexposure.

ObjectiveTo investigate the national prevalence of potentially inappropriate medications (PIMs) prescribed in ambulatory care clinics in Taiwan according to three different sets of regional criteria and the correlates of PIM use.DesignCross-sectional study.SettingThis analysis included older patients who visited ambulatory care clinics in 2009 and represented half of the older population included on the Taiwanese National Health Insurance Research Database.ParticipantsWe identified 1 164 701 subjects who visited ambulatory care clinics and were over 65 years old in 2009.Primary and secondary outcome measuresPIM prevalence according to the 2012 Beers criteria, the PIM-Taiwan criteria and the PRISCUS criteria was estimated separately, and characteristics of PIM users were explored. Multivariate logistic regression analysis was used to determine patient factors associated with the use of at least one PIM. Leading PIMs for each set of criteria were also listed.ResultsThe prevalence of having at least one PIM at the patient level was highest with the Beers criteria (86.2%), followed by the PIM-Taiwan criteria (73.3%) and the PRISCUS criteria (66.9%). Polypharmacy and younger age were associated with PIM use for all three sets of criteria. The leading PIMs detected by the PIM-Taiwan and PRISCUS criteria were all included in the 2012 Beers criteria. Non-COX-selective non-steroidal anti-inflammatory drugs in the Beers criteria and benzodiazepines in the PIM-Taiwan and PRISCUS criteria accounted for most leading PIMs.ConclusionsThe prevalence of PIMs was high among older Taiwanese patients receiving ambulatory care visits. The prevalence of PIM and its associated factors varied according to three sets of criteria at the population level.
